This AC focuses on the use of dynamic test methods for evaluating the performance of airplane seats, restraint systems, and related interior systems for demonstrating structural strength and the ability of those systems to protect an occupant from serious injuries sustained in …

When a side-facing seat is being analyzed, the v-ATD should be a part 572, subpart U, ES 2RE Side Impact Crash Test Dummy, 50th Percentile Adult Male; and the applicant should demonstrate that the v-ATD is calibrated to behave similarly to the physical ATD unless the standards in SAE ARP 5765, Revision A are met.

Ten types of seats (two and three place coach seats, one first class seat, five business jet seats and two side facing seats) have been modeled and analyzed for FAR 25.562 or 23.562 dynamic test conditions:

This test requires simulating deformation between the seat and airplane floor by deforming the test fixture, as respectively prescribed in Figures 6 and 7 for single occupant and multiple occupant seats, prior to applying the dynamic impact conditions.

Certification programs include 16G crash simulation and flammability testing of seat materials. The importance of endurance testing cannot be understated, as it confirms the quality of the product and also gives airline customers confidence that their seats will withstand the rigors of passenger use for the long haul.

1995年5月1日 · Since 1988, newly type certificated aircraft are required to comply with stringent crashworthiness requirements. Central to these more stringent requirements is a dynamic test that assesses the potential for injury for someone exposed to similar conditions. In this paper the techniques and reference

AC 20-146: Methodology for Dynamic Seat Certification by Analysis for Use in Parts 23, 25, 27, & 29 Airplanes and Rotorcrafts Signed in May 2003; allows simulation results to be used in support of seat certification

The process and guidelines for CBA are described in advisory circular AC20-146 developed by the FAA. This paper describes NIAR’s procedures and testing protocols and shows the prediction and validation correlation results after applying those to an actual 3-places commercial seat using the finite element explicit code LS-DYNA.

Currently, the aerospace industry spends large amounts of resources certifying aircraft seats. The main objective of this presentation is to demonstrate that the current NIAR-VIMOTECH dynamic seat modeling methodology is able to support industry during the certification process by the means of numerical analysis.

This Notice of Proposed Amendment (NPA) addresses a safety issue related to the crashworthiness of passenger and crew seats in order to mitigate the risk of subsequent injuries or deaths. CS-25 provides specifications to protect large aeroplane occupants from serious injury in case of emergency landing.
